If an extra phy0 up happens during resume of the SAS controller, it will emit a new libsas event (event PORTE_BYTES_DMAED and event DISCE_DISCOVER_DOMAIN). We will call function scsi_sysfs_add_sdev() in event DISCE_DISCOVER_DOMAIN, which will call __pm_runtime_set_status() to resume supplier (host controller). For runtime PM core, if device is in the resuming state, the later resume request of the device will wait for previous resume request to complete synchronously. At that point in time the state of the controller is still resuming as it waits for all libsas events to be completed, while libsas event DISCE_DISCOVER_DOMAIN is blocked as the state of the controller is resuming which causes a deadlock. To avoid the issue, filter out new PHY up events while the controller is suspended.

2020-10-07scsi: hisi_sas: Use hisi_hba->cq_nvecs for calling calling synchronize_irq()Luo Jiaxing1-2/+3
A call trace is observed when running function level reset with online CPUs less than 16 and MSI auto-affinity enabled. [16538.348038] Call trace: [16538.348422] pci_irq_vector+0x98/0xc0 [16538.348947] disable_host_v3_hw+0x8c/0x288 [hisi_sas_v3_hw] [16538.349706] hisi_sas_reset_prepare_v3_hw+0x60/0x88 [hisi_sas_v3_hw] [16538.350631] pci_dev_save_and_disable+0x38/0x68 [16538.351290] pci_reset_function+0x44/0x88 [16538.351846] reset_store+0x6c/0xb8 [16538.352429] dev_attr_store+0x44/0x60 [16538.353035] sysfs_kf_write+0x58/0x80 [16538.353558] kernfs_fop_write+0x140/0x230 [16538.354175] __vfs_write+0x48/0x80 [16538.354675] vfs_write+0xb8/0x1d8 [16538.355145] ksys_write+0x74/0xf8 [16538.355615] __arm64_sys_write+0x24/0x30 [16538.356240] el0_svc_common.constprop.4+0x80/0x1f0 [16538.356905] do_el0_svc+0x2c/0x38 [16538.357408] el0_svc+0x14/0x40 [16538.357848] el0_sync_handler+0xbc/0x2ec [16538.358388] el0_sync+0x140/0x180 The reason is that if we use pci_alloc_irq_vectors_affinity() to allocate IRQs, the number of CQ IRQs can only be less than or equal to the number of online CPUs, but we use hisi_hba->queue_count (always 16) to iterate during interrupt_disable_v3_hw(). Use hisi_hba->cq_nvecs to replace hisi_hba->queue_count to avoid synchronize IRQ on a CPU which does not exist.

2020-10-03scsi: be2iscsi: Fix a theoretical leak in beiscsi_create_eqs()Dan Carpenter1-2/+2
The be_fill_queue() function can only fail when "eq_vaddress" is NULL and since it's non-NULL here that means the function call can't fail. But imagine if it could, then in that situation we would want to store the "paddr" so that dma memory can be released.

2020-10-03scsi: fnic: Do not call 'scsi_done()' for unhandled commandsHannes Reinecke1-2/+1
The fnic drivers assigns an ioreq structure to each command and severs this assignment once scsi_done() has been called and the command has been completed. When traversing commands to terminate outstanding I/O we should not call scsi_done() on commands which do not have a corresponding ioreq structure; these commands have either never entered the driver or have already been completed.
